Therefore, the optimal gateway can be automatically found for each lower-hanging device, each lower-hanging device can be automatically transferred to the corresponding optimal gateway, the network condition of the lower-hanging device is not required to be manually detected one by one manually, the optimal gateway is manually screened and the optimal gateway is manually transferred, and the device transfer efficiency in a multi-cascade hierarchical gateway scene is greatly improved.
In one embodiment, the control instruction is used to instruct each of the off-hook devices to acquire issue time information corresponding to the control instruction and acquire receive time information corresponding to the local receive control instruction, and calculate a response delay corresponding to each of the off-hook devices according to the issue time information and the receive time information, and use the response delay corresponding to each of the off-hook devices as a response processing result of each of the off-hook devices. Determining a device to be migrated from a plurality of devices hanging down, comprising: acquiring response delay corresponding to each lower hanging device; and if the response delay corresponding to the equipment to be hung is greater than the time length threshold, determining the equipment to be hung with the response delay greater than the time length threshold as the equipment to be migrated.

In the process of transmitting the control instruction from the control device to the drop-on device, the hop count calculation algorithm updates the hop count information (the hop count is increased by one) every time the drop-on device passes through one device until the drop-on device receives the control instruction. And after receiving the control instruction, the drop-off device identifies and acquires hop count information in the control instruction, takes the hop count information as the cascade hierarchy of the drop-off device, and generates a response processing result based on the cascade hierarchy and returns the response processing result to the control device. It should be noted that the more the number of hops that the control command is issued to the drop device, the higher the possibility of network delay, and therefore, the drop device with the larger number of hops needs to be migrated. After the control device receives the response processing results returned by the lower-hanging devices, the cascade level corresponding to each lower-hanging device is identified from each response processing result, and if the cascade level corresponding to the lower-hanging device is larger than a preset cascade level threshold, the corresponding lower-hanging device is determined to be the device to be migrated.
